Anvil 4351011460 Steam Service Ball Valve 1-1/4 in

Product Description

The ANVIL 4351011460 is a 1-piece carbon steel manual ball valve rated for steam service applications. It features a standard port design with female NPT connections on both ends, a locking lever handle, and Graphoil seals that hold up under high-temperature, high-pressure steam conditions. The valve carries a maximum working pressure of 2000 psi, making it suitable for demanding industrial and commercial piping systems. It is installed by licensed plumbers, pipefitters, and mechanical contractors working on steam distribution and heating infrastructure.

This valve is sized for 1-1/4 inch pipe and uses FNPT x FNPT end connections conforming to ASME B1.20.1 NPT threading standards. The standard port ball valve design is a common choice in steam service lines where full shutoff capability and reliable reseating are required. The locking lever handle provides a positive open and closed indication and resists unintended actuation in live piping environments. It is well suited for both new construction and retrofit work on commercial steam heating and process piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter. Depressurize and drain the steam system fully before removing or installing any valve. Apply appropriate thread sealant rated for steam service to all NPT connections per the manufacturer and applicable ASME or IFGC guidelines. Verify valve orientation and flow direction prior to pressurizing the system.
